pathlib: Object-oriented filesystem paths

• pathlib module

  • offers classes representing filesystem paths with semantics appropriate for different operating systems.

• Path classes are divided between pure paths, which provide purely computational operations without I/O, and concrete paths, which inherit from pure paths but also provide I/O operations.

Concrete Paths

class pathlib.Path(*pathsegments)

• represents concrete paths of the system’s path flavour(instantiating it creates either a PosixPath or a WindowsPath)

• Attributes

Attribute	Description
root	A string representing the (local or global) root
anchor	the concatenation of the drive and root
parents	the logical ancestors of the path
parent	The logical parent of the pat
name	the final path component, excluding the drive and root
suffix	The file extension of the final component
suffixes	A list of the path’s file extensions:
stem	The final path component, without its suffix

• Methods

Method	Description
as_posix()	Return path string with forward slashes
joinpath(*other)	Combine the path with each of the other arguments in turn

• Example:

print("\n------- pathlib.Path(*pathsegments)--------\n")

from pathlib import Path

f_path = Path(__file__)

print(f_path)       # c:\Users\simon\Desktop\demo.py

# Attributes
print(f_path.root)          # \
print(f_path.anchor)        # c:\
print(f_path.parents)       # <WindowsPath.parents>

[print(p) for p in f_path.parents]
# c:\Users\simon\Desktop
# c:\Users\simon
# c:\Users
# c:\

print(f_path.parent)        # c:\Users\simon\Desktop
print(f_path.name)          # demo.py
print(f_path.suffix)        # .py
print(f_path.suffixes)      # ['.py']
print(f_path.stem)          # demo

# Methods
print(f_path.as_posix())    # c:/Users/simon/Desktop/demo.py
print(f_path.joinpath("dir1", "dir2"))    # c:\Users\simon\Desktop\demo.py\dir1\dir2
print(Path().joinpath("dir1","dir2"))       #dir1\dir2
